Different rims with more off set.
More aggressive tires without chains.
Rope snow chains.
Homemade tire chains made from smaller chain.
Cut the frame :laughing:
...just brain storming
Have a Gravely ZT60HD. Bought a set of chains so that we could mow a steep bank. Problem is the chains will not go on because the tires sit right next to the frame and there is not enough room for chains. Gravely was of no help. Is there modifications for this.
